In this embodiment, wear to be equipped with three bolt on the mounting panel 201, three bolt is with the even circumference distribution of axis of mounting panel 201, and the bolt is located the border department setting of mounting panel 201. When the damper 1 is attached, the attachment plate 201 and the vehicle body are fixed by bolts, and the front end of the damper 1 can be connected to the vehicle body.
Referring to fig. 2 and 3, the cover plate 3 seals the top end of the sleeve portion 202 and fixes the sleeve portion 202, the piston rod 101 of the shock absorber 1 is inserted into the sleeve portion 202 and inserted into the cover plate 3, and the top end of the piston rod 101 of the shock absorber 1 extends out of the cover plate 3, so that the shock absorber 1 is convenient to assemble and disassemble, and meanwhile, the piston rod 101 can be connected with the guide tool through the exceeding part of the piston rod 101.
Referring to fig. 1 and 3, a first positioning structure 4 is arranged on the surface of the cover plate 3, the cover plate 3 is connected with a guiding tool in a matching mode through the first positioning structure 4, when the shock absorber 1 is installed, the upper support 2 is connected with the guiding tool in a matching mode through the piston rod 101 and the first positioning structure 4, and the upper support 2 is driven to move to a corresponding installation position of an automobile body conveniently through guiding of the guiding tool.
Set up like this, because the setting of first location structure 4, when installing shock absorber 1, the cooperation of first location structure 4 on direction frock and the apron 3 and be connected with apron 3, the direction frock is connected with shock absorber 1's piston rod 101 cooperation simultaneously, first location structure 4 and piston rod 101 have shared upper bracket 2 jointly and have been connected required intensity with the direction frock, therefore need not extension design piston rod 101, the weight of shock absorber 1 has been alleviateed, the length that piston rod 101 stretches out apron 3 shortens, the packing to shock absorber 1 has been made things convenient for, and piston rod 101 is difficult for stretching out the length overlength and is bruised, shock absorber 1's transportation has been made things convenient for.
Optionally, the first positioning structure 4 includes a plurality of positioning holes, the positioning holes are disposed on a surface of the cover plate 3 deviating from the upper support 2, and the positioning holes are used for matching with the guiding tool.
Referring to fig. 1, the first positioning structure 4 includes a plurality of positioning holes, and the plurality of positioning holes are all opened on the surface facing away from the upper support 2, i.e. the upper surface of the cover plate 3. The guide tool is matched with the positioning hole, so that the cover plate 3 is connected with the guide tool. In this embodiment, the guiding tool is in insertion fit, clamping fit or threaded fit with the positioning hole, so that the guiding tool is connected with the cover plate 3 through the positioning hole.
Set up like this, the setting of locating hole, the direction frock can be connected with apron 3 with the locating hole cooperation to this bearing capacity of having shared direction frock and piston rod 101 junction, shift the main hookup location of upper bracket 2 and direction frock to direction frock and apron 3 on, because piston rod 101 bears the weight of diminishing with being connected of direction frock, need not to utilize piston rod 101 to be connected with the direction frock even, therefore need not to extend design piston rod 101, can accomplish the stable connection of direction frock and upper bracket 2. Meanwhile, the weight of the cover plate 3 is reduced due to the design of the positioning hole, the weight of the shock absorber 1 is reduced to a certain extent, and in addition, the length of the piston rod 101 is shortened, the weight of the shock absorber 1 is also reduced, the shock absorber 1 is convenient to lighten, and the shock absorber 1 is convenient to transport.
Optionally, the positioning holes include two first positioning holes 401, the two first positioning holes 401 are uniformly distributed circumferentially along the axis of the shock absorber 1, and the guiding tool is correspondingly matched with a plurality of positioning holes through matching with the first positioning holes 401.
Referring to fig. 1, the positioning holes include two first positioning holes 401, and the two first positioning holes 401 are used to assist the guiding tool to be quickly matched with the plurality of positioning holes. The two first positioning holes 401 are uniformly distributed circumferentially around the axis of the damper 1, i.e., the two positioning holes are symmetrically arranged on a plane of symmetry of the cover plate 3. In the process that the guide tool is matched with the positioning holes, the first positioning holes 401 play an indicating role, and after the guide tool is matched with the two first positioning holes 401, the guide tool can be quickly matched with the rest positioning holes. Simultaneously, set up two first locating hole 401, after direction frock and two first locating hole 401 cooperations, be difficult for taking place relative rotation between direction frock and the upper bracket 2, make things convenient for the installation of follow-up upper bracket 2 and automobile body.
Set up like this, the setting of first locating hole 401, because two regularity that first locating hole 401 set up the position, make things convenient for the direction frock to cooperate with first locating hole 401 fast, after direction frock and first locating hole 401 cooperation, all the other locating holes on the apron 3 can correspond the connection structure setting on the direction frock, can be fast with direction frock and a plurality of locating hole cooperation, improved shock absorber 1's installation effectiveness.
Optionally, the positioning holes further include two sets of second positioning holes 402, and the guiding tool is matched with the second positioning holes 402 to reinforce the connection between the guiding tool and the cover plate 3.
Referring to fig. 1, the positioning holes further include two sets of second positioning holes 402, and the two sets of second positioning holes 402 are matched with the guiding tool to reinforce the connection between the guiding tool and the cover plate 3. In this embodiment, the number of the second positioning holes 402 in each group is preferably three, and in other embodiments, the number of the second positioning holes 402 in each group may be set to other numbers. The distance between adjacent second positioning holes 402 in each group of second positioning holes 402 is consistent, the distance between the second positioning holes 402 and the first positioning holes 401 is larger than the distance between the adjacent second positioning holes 402, so that the first positioning holes 401 and the second positioning holes 402 can be conveniently distinguished, and when the guiding tool is connected, a worker can conveniently and quickly find the first positioning holes 401 to be matched with the guiding tool.
Set up like this, the tie point of direction frock and apron 3 has been increased in the setting of second locating hole 402 for the direction frock is connected more stably with apron 3, and when direction frock direction drove upper bracket 2 and removed, upper bracket 2 was difficult for breaking away from with the direction frock, has made things convenient for shock absorber 1's installation.
Alternatively, two sets of the second positioning holes 402 are uniformly distributed circumferentially about the axis of the shock absorber 1.
Referring to fig. 1, two sets of second positioning holes 402 are uniformly distributed circumferentially around the axis of the shock absorber 1, and the two sets of second positioning holes 402 are respectively located at two opposite sides of the connecting line of the two first positioning holes 401. On one hand, the positions of the second positioning holes 402 are uniformly arranged, so that the connection between the guiding tool and the cover plate 3 is more stable. On the other hand, since the two sets of second positioning holes 402 are uniformly and circumferentially distributed, the second positioning holes 402 can be aligned as long as the guiding tool is aligned with the first positioning holes 401, and the efficiency of connecting the guiding tool with the cover plate 3 is improved.
